Abstract
A wireless transmitter waterproof damp-proof toolbox used for cooling tower testing comprises an aluminum foil box body (1), an aluminum foil box cover (2), waterproof aviation joints (3), a waterproof cloth sleeve and a liner waterproof sealing bar; the aluminum foil box body is used for accommodating a wireless transmitter; the size of the box body is slightly larger than the size of the wireless transmitter, so that collision of the box body and the transmitter when the wireless transmitter waterproof damp-proof toolbox is carried by a user can be prevented; after the transmitter is installed in the box body, the box body is covered with the aluminum foil box cover; a combination surface of the aluminum foil box cover and the aluminum foil box body is sealed through the liner waterproof sealing bar; the aluminum foil box body is provided with two waterproof aviation joints; an interface of a measuring element, which is connected with the wireless transmitter, is transferred to the box body; a small hoe is formed at the top of the aluminum foil box cover; one waterproof cloth sleeve used for accommodating the antenna of the wireless transmitter is pasted at the hole of the box body, so that a shielding effect of the aluminum foil box body, which is exerted on wireless signals, can be avoided. The wireless transmitter waterproof damp-proof toolbox used for cooling tower testing of the utility model has the advantages of being simple and practical and portable, and excellent waterproof performance, and will not affect the transmission of the wireless signals when realizing waterproof and damp-proof functions, and is very suitable for cooling tower test environments.
Description
technical field
The utility model relates to a kind of waterproof and dampproof tool box of wireless transmitter for cooling tower test, belongs to electric system testing equipment tool box special technical field.
background technology
Counter flow type natural draft cooling tower is as the important component part of fired power generating unit s cold end system, and the quality of its thermal performance will directly affect the vacuum of unit, and then affects the safety and economic operation of unit.Heating power calculates and shows, raise and cause 1 DEG C of the every rising of delivery temperature of steam turbine because cooling tower goes out tower circulating water temperature, heat consumption rate increases 35-40J/Wh, can cause the Steam-water Flow of Turbine Flow Path and therrmodynamic system equipment bigger than normal simultaneously, the long-term safety operation of main and auxiliary machine has been formed to threat.Based on above-mentioned factor, the operation maintenance of cooling tower, technological transformation and thermal performance test are significant.
Cooling tower is to contact with water by air, carries out heat, matter transmission, the heat in recirculated water is brought into the equipment of air.Going out tower air wet and dry bulb temperature is that cooling tower performance is calculated important measurement parameter, the accuracy of this parameter measurement is calculated most important to cooling tower performance, traditional test method is to be evenly arranged glass thermometer along tower inner cross groove aisle, remove at regular intervals to read one by one in tower thermometer numerical value, or adopting temperature transmitter to connect platinum resistance connects data acquisition board and measures, these methods have following drawback: (1) can not obtain continuous measured temperature, and test findings accuracy is had a certain impact; (2), in the environment that is exposed to high humility of a large amount of transmitters, compensating wire, four-core data line, waterproof and dampproof problem is the key of restriction test; (3) cooling tower test is carried out conventionally in the time that summer temperature is higher, and the interior temperature of tower is high, high humidity, needs a large amount of people's power wirings, wiring, take-up, reading etc., and testing crew labour intensity is large.For this reason, adopt wireless transmitter in tower, to carry out the labour intensity that continuous data measurement improves the precision of test and reduces test, in cooling tower, humidity is more than 80%, the long-term placement of wireless transmitter wherein can cause device damage, therefore necessary for the corresponding waterproof and dampproof tool box of wireless transmitter design.
summary of the invention
The purpose of this utility model is, according to the situation of wireless transmitter working environment, a kind of waterproof and dampproof tool box of wireless transmitter for cooling tower test is provided, it have advantages of easy to carry, assemble simple, waterproof and dampproof performance good, do not affect wireless signal transmission.
The technical solution of the utility model is that the utility model is made up of aluminium foil casing, aluminium foil case lid, waterproof Aviation Connector, waterproof cloth cover, liner water-proof sealing strip.Aluminium foil case lid is arranged on the upper opening place of aluminium foil casing; Waterproof cloth cover is arranged on case lid tapping in aluminium foil case lid; Waterproof Aviation Connector is arranged on respectively on aluminium foil casing two sides; Liner water-proof sealing strip sticks on aluminium foil box house.
Aluminium foil cabinet design becomes the rectangular box structure that size is suitable with wireless transmitter, for laying wireless temperature transmitter, and casing and transmitter collision while preventing from carrying; The Aviation Connector that wireless transmitter is connected with measuring sensor expands to tank surface, and the aviation adapter of tank surface adopts water proof type, and wireless transmitter can be connected with measuring sensor in casing; Above aluminium foil case lid, have an aperture suitable with wireless transmitter antenna size, paste a waterproof cloth cover at case lid tapping, this waterproof cloth cover adopts charge garment waterproof cloth material, for preventing the shielding of aluminium foil casing to wireless signal, when test, the antenna of wireless transmitter is put into waterproof cloth cover through aperture, in waterproof, do not affect the transmission of wireless signal; Liner waterproof strip of paper used for sealing is one deck water-proof sealing strip that cabinet interior is pasted, and extends upwardly to case lid along casing surrounding, and the commissure at casing and case lid in the time that case lid closes forms water-proof sealing strip, and block water steam enters casing from commissure.
The beneficial effects of the utility model are; a kind of waterproof and dampproof tool box of wireless transmitter for cooling tower test that the utility model provides; can in the time that testing, cooling tower well protect wireless transmitter not to be subject to the impact of water, vapour, wet environment; and do not affect the signal transmission of wireless transmitter, easy to carry, assembling is applicable to site work and uses simply very much.
